Addition & Subtraction

Recall from the very early years of your education that addition means adding a group of numbers together.  Addition is almost always signified by the + symbol.

Example:  5 + 4 = 9

Subtraction means taking the value of one number away from the value of another number.  Subtraction is almost always signified by the symbol.

Example:  8 – 4 = 4

Note that the result of an addition problem is known as the sum, and the result of a subtraction problem is known as the difference.
